GRAIDLCAR DOOR.

Specification of Letters Patent.

Patented my ie, isos.

Application led May 171907. Serial No. 374,187.

Toall whom it 'may concern:

Be it known that I, WiNFiELn S. DRisirnLL, a citizen of the United States, residing at Gretna, in the county of Sarpy and State of Nebraska, have invented certain new and useful Improvements in Grain-Car Doors, of which the following is a specification.

My invention relates to improvements in grain par doors, and has for its object the provision of a grain tight 'door which shall e simple, durable and ractical, consisting of but, few parts, and W lch may be readily operated to facilitate the loading or removal o the grain from the car either in bulk or in limited quantities.

Another object of my invention is to rovide a door arranged in independent sections so that one or more of the door sections may beremoved or replaced at will according to dierent requirements, and also to provide a hinged lower door section which may be operated from the outside and hinged upwardly out of the way, for removal of the grain in small quantities.

I aiin to accomplish the above in a practical and efficient manner and to such ends, iny invention consists of vertically movable and swinging independent door sections, and' a lower door section having hinge connection'with the next adjacent door section said lower door section of shorter length than the other. door sections and having eXtensible ends operated from the outside of thc door; and the invention further comprises agrain door possessing certain other novel features of construction, combination and arrangement of parts substantially as disclosed herein and as illustrated in the accompanying drawings, in which.;

'Figure 1, is a front elevation of my 1in ,proved grain door taken from the outside of thecan `Fig. 2, isa rear elevation taken from the inside of the car. Fig. 3, is a vertical sectional view of the door iii closed position, the dotted lines indicating the different positions of the' door sections. 'Fig. 4, is a broken sectional view of one end a ,of` vthe lower door section showing its connection with'the next upper door section.

Fig. 5,is a detached perspective View of one of the hook members which serve to sup ort upper door section. Fig. 6, is a bro en sectional view on the line 6-6 of Fig. 4,

showing the extension plate in engagement with the depending grooved guiding strip.

Referring vto the drawings: The numeral l, designates the door frame of an ordinary car, and to the inner face ofthe door franie cured to the inner face -of each of the door posts parallel to the strips, and oifset brackets 4, are secured to the door frame adjacent the upper terminal of the guide rods, these brackets being in the form. of a double loop as shown in Fig..2, to form hangers.

Tliedoor itself is preferably arranged in three sections, an upper', interniediateand lower section, the upper and intermediate door sections being of the proper length to properly iit between the guiding strips or cleats 2, the body of the lower door section being shorter, or only as long as 'the door frame is wide. The upper door section 5, is provided with strengthening or stifening straps 6, at its ends, these straps being directed outwardly in an angular portion 7, at the upperedge of 4the door, thencey directcd laterally in a straight horizontal portion 8, and iinally terminating in a hook 9.

Rings 10, slidably confined upon the guide rods, are passed over the horizontal portions of the hook members, thereby sewing to slidably secui'e the upper 'door section to the guide rods at the saine time leaving it free for l portion 13, terminating in a hook 14, these hooks being of substantially the saine shape as the suspending hooks on the upper door section. Rings 15, serve to hold the intermediate door section in position'with respect to the guide rods in the same manner as the upper section is held, and it willbe seen that i by slipping the rings over the hooks, the section niay be entirely renioved from the door frame. 'Additional securing 'means for the intermediate section are provided in the form of stationary**hooksv 16, which are mounted on the vertical guiding/strips 2, so as to engage the lateral or horizontal portion of the supporting hooks on this section. Angular corner strips or binding strips 17, are applied to the inner corners of the intermediate section, these binding strips being extended downward in the form -of groovedy guiding extensions 18. These guiding extensions rest flat against the face of the door posts and form Ilegs for the support of the intermediate door section Stop blocks 19, on the floor of the car serve to hold these socalled legs in close engagement with the face of the door posts, so that in order to remove this door section, it is necessary to lift it until the legs clear these stop blocks and then free the hooks of the rings. The upper face ofthe stop blocks is preferably inclined as (shown in order to facilitate replacing of the oor.

Als before explained, the lower door section 20, is only aslong as the' door frame is wide, as this section is adapted to be hinged up from the outside of the dor frame.. Secured to the upper edge of the lower door section by brackets 21, is a pivot rod 22, the rod being spaced above the edge of the section, theends, of the rod extending beyond the bracket and engaged in the slotted supporting brackets 23, thereby serving as pintles for the support of this lower section. The slotted hinge brackets 2 3, are secured near the lower edge of the intermediate section, the slotted por-l tion of the brackets being inclined upwardly at an angle as at 24, so as to allow the lower section when being vhinged, upward, to clear the door sill 25.

The outside face of the lower door section is recessed at its ends at 26, and end extension plates27, are adapted to be seated in' said recessed ends ush with the face of the section; The'extension plates are each provided with two or more transverse 'slots 28,

. -through which are passed the headed fastening boltsor screws 29, which serve to slidably secure the extension plates in the recessed ends of the door section. These extension plates are adapted for engagement with the grooved guiding extensions depending from the intermediate door vsection and are oper-- atedin the following manner 5 an operating lever, 30, is eitherformed integral wither/is b pfateson the ends of the lower door section connected to a transverse'bar or plate 31, which is pivoted transversely upon the lower section in journal brackets 32, the lever as a whole being of T-sha'pe. The ends of the transverse portion of the lever are widened and slotted as at 33, and connecting links 34, secured tothe extension plates are pivotally connected to the widened and slotted portions of the lever as shown in Fig. l, so that rocking the operating lever the slidable are either extended and caused to engage the-v groeved guiding extensions or arewithdrawn.

seaaae from engagement therewith, at will. Turn buttons 35, serve to hold the operating lever flat against the lower section, thereby locking the` extension plates either extended or withdrawn 'as desired. The meeting edges of the dierent door sections are preferably cut at an incline as shown in the sectional view sov as to'prevent leakage of any Of the grain.

. When the door is entirely closed, the upper edge of vthe upper door section is secured against movement by means of the latches 36, which are pivoted to the sides of the door frame and the lower corners of this u per section are engaged by the angular and orizontal portions of the supporting hooks on -the middle door section as shown in Fig. 2, so that the upper door is locked against all movement. The inner faces of the door sections are preferably paneled or braced as shown, as this construction greatly strengthens the sections and prevents vthem from warping.

In unloading the grain, the lower door is opened from the, outside by throwing the operating leversL ier, thereby releasing the extension plates from engagement with the ing free so"tha the way. f- The doorwmaybeiflded up against Y. the car roofentirely out of the way as shown in dotted vlines 'in Fig. 3. In order to fold tion is first lifted until the supporting hooks thereon engage the upper loops in the looped supporting brackets or hangers Il,l and this section is then hinged up against the car roof 'upon the hangers as a pivot and held in position against the car roof by a depending latch 37 `The intermediate door section carrying the lower section is then lifted until the suspending hooks thereon engage the lower loops in-the bracket hangers, when it is hinged upward in the same manner as the upper section, parallel to the' up er section as will be readily understood an it is there held by means of'a de ending catch similar to the catch 37, (not sfiown).

connection with the drawings, it will b'evident that l have provided a thoroughly racv.tical and desirable grain car door whic accomplishes all the results herein set forth as to manner.
